5) The main optical unit is attached to the equatorial mount with a black cast metal
mounting plate. This mounting plate has four chromed screws mounted in it. Remove
all four screws. The mounting plate has one smooth face and one face with small
ridges. Place the smooth face against the underside of the main optical unit. Then
insert the two slotted chromed screws through the inner holes so that they engage
with the two threaded holes on the underside of the main optical unit. Tighten these
with a screwdriver (See Fig. 4).

6) Position the main optical unit, with the mounting plate attached, over the equatorial
mount as shown in Fig. 5. Insert the two chromed screws with the Phillips (+) heads into
the two holes in the equatorial mount so that they engage the two holes at the ends of
the mounting plate. Tighten with a screwdriver (See Fig. 6 and Fig. 7).
